So, Kevin O'Leary went off on TV again, and just like manyofhisappearances, it was awkward and embarrassing.

This time his target was French economist Thomas Piketty and his book "Capital in the Twenty-First Century," which argues that extreme inequality could result from capital returns exceeding economic growth.

Piketty advocates a wealth tax as a way of countering constantly rising inequality, and argues that the problem cannot be tackled by market forces, CBC News reported.

O'Leary predictably pounced on this idea on Thursday's "Lang and O'Leary Exchange," taking Piketty's arguments to their extremes.

Lang: So a book that has garnered worldwide attention and accolades merits no discussion, in your view, Kevin O’Leary, we should just move on, because you don’t like how it sounds?

Kevin: I’m talking about the part where he says let’s redistirubte the wealth. Redistribution of wealth doesn’t work, we tried it in the Soviet Union, North Korea, would you like to live there? How about Cuba?"

The debate goes on like this until O'Leary accuses Lang of being "against success." She says she's not against success, but "selfishness, narcissism and lies."
